Apple computers are notoriously resilient to viruses and malware which is one of the reasons why they are so reliable (and expensive). Until recently Mac viruses, malware, adware and other malicious items were almost impossible to encounter but now hackers are targeting the Mac OS very aggressively.
This is true that Macs can get viruses. Mac owners argue that the Mac operating system is without a doubt superior to Windows and because of this it cannot be easily affected by viruses. Apple support system says that the Unix core that the Mac OS is built on prevents Mac computers from being susceptible to computer viruses. That’s why it’s nearly impossible to get your Mac infected.
There is another reason why it’s far less likely to get a virus on a Mac rather than a PC. Since Macs only make up 5% of the market share, a programmer would have to commit many months discovering how to program viruses for Macs and then spend many months making the virus all simply to target only 5% of the market. Another advantage for Macs is that the Mac OS X is actually significantly more difficult for coders to learn about than Windows operating systems. It is possible but requires a good deal of an effort.
At the same time, there are lots of other unwanted pieces of software that can affect your Mac, such as adware, malware, and mining programs which can generate traffic, display unwanted ads, manipulate search results redirecting you to some questionable websites, and even record keystrokes to steal your passwords, credit card information and other sensitive data. These programs often get downloaded in a bundle with another app.
Some of the common signs that your computer has been infected with malware are pop-up banners, fake app update requests. Your Mac can become significantly slower as if something on the background is consuming its resources. Here are the tips on how to remove any bits of malicious code on your machine.
How Can You Remove A Virus From Your Mac
- Go to Launchpad and check if any apps have been installed without your knowledge. Immediately uninstall them and empty Trash. Look out for names like MacDefender, MacSaver and similar.
- Launch Activity Monitor from the folder called Utilities in the Applications folder.
- Click on All Processes from the pop-up menu which you can see in the top right corner of the window.
- Under Process Name column, search for the name of the installed app and select it by clicking on it.
Select Quit Process.
- Go to the Applications folder and send this app to Trash.
If you notice that a malware has been installed to your Mac, you must not provide the credit card information or any other information of sensitive nature under any circumstances.
After removing any suspicious bits of data, restore your operating system from the backup made by Time Machine or any other trusted backup app downloaded from AppStore. Make sure to install only the backup from before the time you think your computer was infected. Reboot your computer.
Once you have restored your Mac from a backup, you should delete the cache of your internet browser. To do this, go to Safari, choose History and select All History from the list. Erase the whole history. To do this in Chrome, go to the main browser menu and choose the option Clear Browsing Data, then add option All Time and proceed to Clear Data.

The best option for Mac owners would be to go out and get anti-virus software designed specifically for Mac OS. Keep in mind that a lot of software that claims to resolve problems with your Mac is actually a malware that can make things even worse. So doing a search for your problem and installing the first app that comes up in search results is not a good idea since search results can be easily manipulated.
